My first project at the new job is a WAP site for a theme park. I've heard about short codes, seen American Idol and know that people can download things to their phones (and are apparently pretty excited about it). In other words, I don't know anything about mobile. So I got online (where else!) and found some amazing resources, thanks to dotmobi (an independent industry group).
They have a blog, a developer's guide, a list of .mobi sites to check out, and the coolest of the cool, a mobile site simulator where you can interact with these sites online as if you were on a phone! I'm so excited (and grateful for dotmobi!)
Diving in now.
